The Nanavati Commission, which probed the 1984 anti-Sikh riots, is likely to submit its report on February 9.
"The report has been finalised and it will be submitted to the Union Home Minister Shivraj Patil on Wednesday," commission sources said.
The commission's term expired on January 31.
The commission headed by Justice G T Nanavati, a retired Supreme Court judge, is the second judicial body to probe the sequence of events that led to violence against the Sikh community in the aftermath of the assassination of the then prime minister Indira Gandhi on October 31, 1984.
The commission was appointed by the previous National Democratic Alliance government in 1999.
